Using Datastax 5.1 version Cassandra, trying to integrate ldap with it. Added required parameters in dse.yaml and cassandra.yaml but when I try to authenticate ldap user then it keeps failing with below error.
[root#ip-11.11.11.11 ~]# cqlsh -u 123456
Password:
Connection error: ('Unable to connect to any servers', {'127.0.0.1': AuthenticationFailed('Failed to authenticate to 127.0.0.1: Error from server: code=0100 [Bad credentials] message="Failed to login. Please re-try."',)})
Here is the message from debug.log.

Looks like its not able to connect to ldap, not binding with it?
I am able to connect to AD using ldapsearch and get result for the user from the cassandra node. Also imported the certificate into the keystore and mentioned it in the dse.yaml. Any pointers?
The issue was with the certificate chain, after using correct intermediate certificates binding with AD was successful.

I am getting error when I try to datastax cassandra instance.
bin/cqlsh -u admin -p PASSWORD -b BUNDLE_ZIP_PATH
Connection error: ('Unable to connect to any servers', \
{'xxx:xxx:xxx': ValueError('No host_id to create the SniEndPoint',)} \
)
Have anyone seen this error? This is a to a cloud managed datastax instance on IBM Cloud and the connection used to work before.
The error is generated by the embedded Python driver that cqlsh uses to connect to clusters. It indicates that it couldn't get the host from the secure bundle.
The most likely cause is that the secure bundle you're using is corrupted so I'd suggest downloading it from the source again. Cheers!
I have a custom Databricks instance with a Domain name that points to an AWS Load Balancer. When I put that information in using either the HTTP instructions here or the databricks cluster instructions here, I get this response in the DBT CLI:
Connection:

port: 443
cluster: 123456-stuff00003

1 check failed:
dbt was unable to connect to the specified database.
The database returned the following error:
>Runtime Error
Database Error
failed to connect
Unfortunately, DBT's debugging logs are terrible and I am not entirely sure why it is failing. I do know that when I connect to the cluster via Intellij I have to provide the CA file, the Client Certificate file, and the Client key file, because I am using a self-signed SSL cert (unfortunately, the self signed cert is required). Also, when defining my ~/.databrickscfg file I have to provide the argument insecure = true.
I've encountered this issue recently and I fixed it by installing root certificates by executing the "Install Certificates.command" script in the python home directory used to run dbt.

I am trying to make a new connection on oracle sqldeveloper as sysdba and when i hit test or connect i got this error message:
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
The default port is 1521, but 1522 is often common.
Check if the database is up. database will not be up causing this issue.
or Check if you are able to connect using sqlplus
I am fairly new to Linux (and brand new to chef) and I have ran into an issue when setting up my chef server. I am trying to create an admin user with the command
sudo chef-server-ctl user-create admin Admin Ladmin admin#example.com
examplepass -f admin.pem
but after I keep getting this error:
ERROR: Connection refused connecting...
ERROR: Connection refused connecting to https://127.0.0.1/users/, retry 5/5
ERROR: Network Error: Connection refused - Connection refused
connecting to https://..., giving up
Check your knife configuration and network settings
I also noticed that when I ran chef-server-ctl I got this output:

I read that this error is due to a prerequisite mistake but I'm uncertain as to what it means or how to fix it. So any input would be greatly appreciated.
Your server does not have a valid FQDN (aka full host name). You'll have to fix this before installing Chef server.
